IVllXlNG MACHINEn Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed May 25,1903. Serial No. 168,741.

To all whom, it nuty concern.-

Be it known that I, PAUL S. WARD, a citi zen of the United States, and a resident of Covington, in the county of Campbell, State of Kentucky, have invented certain new and useful Improvements in Mixing-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of-this specification.

My improvements relate to machines for mixing any desired material, but more par ticularly for the mixing of heavy paste and masses of a doughy nature, consisting of amining-chamber hung in a suitable framework so as to permit of its being easily tipped from its normal position, so that it may be filled or emptied with facility, the mixing-receptacle being provided with a power-driven agitator for mixing the mass of material.

The improvements consist of a certain novel construction and arrangement of parts, to be hereinafter particularly pointed out and claimed, whereby the mixing-trough may be tipped either by hand or automatic ally by the driving power of the machine, and the improvements are illustrated either as applied to any of the well-known constructions of mixers now in use and driven by belt and pulley or otherwise or as applied to that certain novel construction of motor-driven machines in which the motor is so mounted that the machine can be set up for o eratidn in the narrowest possible space wit out liability of the motor mechanism failing to work properly by reason of improper adjustment or alinement with the operative gearing of the machine proper.

It frequently happens drive mixing-machines by motors that the results are unsatisfactory, not because the motor or the mixer is improperly constructed, but by reason of the fact that the motor has been set up or has shifted out of proper alinement.

That certain novel construction, hereinafter described, in which the motor mechanism is located within the frame of the mixer, so as to occupy no extra space and so that there is no liability of shifting of alinement between the mechanisms, also forms an additional when it is sought to feature of my improvements to be set forth in the claims.

In the drawings, Figure 1 is an end elevation of my improved motor-driven mixingmachine. Fig. 2 is a detail sectional plan view of the clutch-gearing for dumping the mixing-trough. Fig. '3 is a side elevation of a belt and pulley driven machine with my improved dumping mechanism. Fig. 4 is an end elevation of same. 'Fig. 5 is. a side elevation of the construction shown in Fig. 1. Fig. 6 is a detail end view of a portion of the mixing-trough, showing a modification of the dumping mechanism.

A is a substantial base-plate on which are securely bolt'ed the standards B B, upon the upper ends of which the mixing-trough D is hung by trunnions through which the agitator-shaft C passes. The agitator-shaft C is journaled in trunnions on the mixing-trough mounted in the upper ends of the standards and is provided with the usual construction of agitator within the mixing-trough, the shaft being rotated by the gear E.

Mounted on the base-plate A between the standards B B is the motor F for driving the agitator-shaft through the gears G E and the pinions H I. The motor can be of any of the well-known constructions, either a water, electric, or compressed-air motor, and the same is mounted on the base-plate A between the standards of the machine to take up the least possible space and in order that when so mounted the motor can be properly coupled with the driving-gear of the machine and so that when once set up it cannot get out of alinement, as frequently happens when the motor is outside the frame of the machine and has to be set up separately.

For the purpose of dum ing the mixingtrough for emptying or filing same I provide as follows: L is a worm mounted on the shaft M, operated by the hand-wheel N. This worm meshes with the segmental-rack teeth O, which segmental rack is connected in any convenient way with the mixingtrough and is concentric with the pivotal su port of the trough, so that by turning tl ie hand-crank the worm will drive the segmentrack to dump the mixing-trough.-

On the inner end of the worm-shaft M is the beveled gear P, which meshes with the loosely on the shaft T, to which the pinion H of the driving-gear is secured. Keyed on this shaft between the loosely-mounted gears R S', so as to slide on the shaft, but rotate with it, is the tapered clutch U. This tapered clutch U is shifted to engage either of the gears R or S by the hand-lever W, the inner end of which is bifurcated and engages the circumferential groove'a on the clutch,

so that by shifting the hand-lever the shaft.

M can be rotated in either direction and the worm L caused to dump or return to its normal position the mixing-trough.

In the construction as illustrated in Figs. 3

and 4., in which the machine is driven by outside power, such as by belt and pulley, the gear E on the agitator-shaft meshes with the gear Y on the driving-shaft Z, and on this shaft the beveled gears S and R are mounted loosely and thrown into and out of engage- 'ment with the beveled gear P by the tapered clutch U, actuated by the hand-lever W.

Instead of mounting the beveled gear P directly on the worm-shaft M it is mounted on the. short vertically-disposed shaft carrying a similar beveled gear I), meshing with the beveled gear 0 on the worm-shaft M, and the worm L is mounted on the end of this shaft and meshes with the gear d on the shaft 6, which in turn carries the gear f, which meshes with the segment-rack O on the mixingtrough. It will be understood, of course,

Without particularly lettering and ointing out the various parts that these beve ed gears and shafts are all properly journaled in suitable journal-boxes at proper points on the frame of the machine. 7

In the construction of dumping mechan ism illustrated in connection with the motordriving devices the worm-shaft and worm are located directly under the segment-rack on the lower edge of the mixing-trough, while in the construction illustrated in connection with the belt and pulley driving devices the worm-shaft and its beveled gears, with their supporting parts, are located outside the frame of the machine, so that it will be evident that my power-dumping construction can be readily adjusted to any of the older dough-mixing machines now in use without altering the construction other than to add the new parts required.

In Fig. 6 I have illustrated a modification of the worm-shaft-dumping device and have substituted therefor the following: Instead of providing a worm L to mesh with a segment-rack O on the trough the shaft M, car- ;rying the gear I, is raised into a vertical position and supported by a yoke Z, loosely mounted on the shaft T, so that the shaft M ber. pivoted on said frame so as to rock, and

provided with a rotatable agitator or agitators, of a train of gears for operating said agi- A tator from suitable power, a segment-rack 1 connected with said mixing-trough, with a .worm-shaft and a worm, and intermediate gearingconnecting said worm and segmentrack, with hand-crank for operating said worm-shaft, a beveled gear on said shaft, beveled gears loosely mounted on a powerdriven shaft of the machine, with clutch for throwing either into operation, a countershaft at right angles to said worm-shaft and the power-driven shaft, with beveled gears thereon, one engaging the worm-shaft gear and the other either of the power-driven shaft-gears whereby the mixing-trough may be dumped either automatically or by hand, substantially as shown and described.

2. In a mixing-machine, the combination with a supporting-frame and a mixing-chamber pivoted on said frame so as to rock, and provided with a rotatable agitator or agitators, of a train of gears for operating said agitator from suitable power, a worm-shaft and a worm, and intermediate gearing connecting said worm and mixing-chamber, with handcrank for operating said worm-shaft, a beveled gear on said shaft, beveled gears loosely mounted on a power-driven shaft of the machine, with clutch for throwing either into operation, a counter-shaft at right angles to said worm-shaft and the power-driven shaft, with beveled gears thereon one engagin the worm-shaft gear and the other either of the power-driven-shaft gears, whereby the mixing-trough may be dumped either automatically or by hand, substantially as shown and described. n I

3. In a mixingqnachine, the combination with a supporting-frame and a mixing-chamber pivoted on said frame so as to rock, and provided with a rotatable agitator or agitators, of a train of gears operating said agitator from suitable power, a se ment-rack connected with said mixing-c amber, with a worm-shaft and a worm, and intermediate agitator-gearing connecting said worm and segment-rack, with a hand-crank for operat- IIO ing said worm-shaft, a gear on said shaft, beveled gear loosely mounted on a powerdriven shaft of the machine, with clutch for throwing either into operation, a countershaft at right angles to said power-driven shaft, and means for connecting said countershaft with said lworm-shaft, whereby the mixing-trough may be dumped either automatically or by hand, substantially as shown and described.
